HOPPER-CAR.

recent To all err/1.0172, it may concern.

ie it known that we, FRANK L. IRWIN and .loim E. Tnssnriiixn, citizensof the United States,-residing at Columbus, in the county of Franklinand State of Ohio, have invent ed certain new and useful Improvements inHopper-Cars, of which the following is a specification.

()ur invention relates to improvements in hopper cars of the typeusually known as the twin-hopper car, and has especial reference totheconstruction of a cross hood and its connection with the sides of thecar, and of reinforcing the same.

The invention further consists in constructing 'a car of this style withthe lower. edge of the plate girder sides arranged in a horizontal planebetween the upper and lower edges of the center sill, the hopperbottoinbeing substantially in the saineplane as the bottom of the centersill.

Referring to the drawings which are here'- to attached and hereby made apart of this specification, Figure 1 is a vertical longitudinal sectionthrough one end of a car taken .on a line between the center sill andone side of the car, showing the center sill hood inside elevation andthe cross hood in section; Fig. 2 is a vertical transverse sectionthrough the car shown in Fig. 1, along the line A-A, showing the crosshood in side elevation; Fig. 3 is a vertical transverse section throughthe cross hood near the side of the car, showing the connection of thecross hood with the side stake and with the sideplate gird.er;Fig. 4t isa perspective showing the cross hood positioned upon the center girder,and the inside side stake connected therewith; Fig. 5 is a verticaltransverse section through the cross hood, show ing the construction ofthe hood and the angle brace extending from one side thereof to theother; Fig. 6 is a vertical section along the median line of the apex ofthe cross hood in Fig. 2 through the center sill,

cross hood, and adjacent portion of the left side of the car, to showespecially the means of uniting the cross hood to the side of thecan-omitting the gusset25 hereinafter described. Fig. 7 is a sectionlooking downward, along the line X-X in Fig; 6.

In the drawings, 1 indicates the center girder of a twin hopper car, thebolster construction being shown generally at 2, the end slope sheets at3, the side of the car at Specification of Letters Patent.

a, the center sill hood at the center girder 1, as seen especially inFigs. 2 and at, cont prises parallel oppositely disposed channels whichare spaced apart as desired, the center. sill hood 5 being mountedthereon and secured thereto through the vertical web thereof, near theupper edge of the center girder, as shown at 6. The door construction isnot shown in these drawings, for it forms no part of this invention, butthe line of the doors when closed is seen at 7 in Fig. 1, the hopperlying between the. end slope sheets and the cross hood, and indicatedgenerally at 7". As seen, the end slope sheets 3 direct the materialnear the end of the car into the hopper to the point of discharge, andone side of the cross hood will direct the material in the oppositedirection into the same hopper, while the other side of the cross hoodwill guide the material into the hopper adjacent to the other end of thecar, where the opposite end slope sheets (not shown) perform thefunction of guiding the material adjacent to the end of the car into thehopper. This style of car, therefore, calls for a cross hood arrangedsubstantially at the middle of the car, and this cross hood extends fromone,

side of the car transversely of the center :girder to the opposite sideof the car, being struction disclosed herein, the cross hood comprisestwo oppositely disposed inclined sheets, 7 and 8, the lower edges ofwhich are reinforced by angles 9, 9 and lie insubstantially the samehorizontal plane as'the bottom of the center girder construction, asappears especially in F l. Sheet Sis bent at its upper end to form aflange 10 thereon at practiially a right angle with the sheet; the sheet7 overlaps the flange 10 and is riveted thereto at 11, across the car. 1The sheets are cutaway and applied to the center sill as appears in Fig.4:, and an angle 12 is arranged with one flange secured to the centergirder at 13, and the other flange secured to the sheet 8 at lat (seeFig. l), thereby forming a secure connection between the center girderand the pears in Fig. 1.

lower portion of the cross hood sheet 8 and is cut away to admit thecenter girder.

similarly connected to the center girder by the angle 15, through therivets l6, asap- A bracing angle member ll is arranged in the cross hoodbetween the side of the car and the center girder, having its ends bentand applied" to the inner faces of the sheets T and 8, as shown at 18and 19, and being securely riveted thereto. It is apparent that the loadhas a tendency to crush the cross hood at this point, and the bracemember 17 furnishes adequate support. A 'similarbracing angle member isprovided for the cross hood on'the opposite side of the center sill, butit is not deemed necessary to show the same in, the drawings.

Referring especially to Fig. 3, the side girder is shown at 20, thelower edge 21 of which is arranged in a horizontal plane above the planeof the bottom of the hopper and center girder, and below the plane ofthe top of the center girder construction; this construction adds to thesymmetry'of the car, saves material and labor and provides facilitiesfor trussing and bracing the car at its sides which render it a valuableimprovement. The cross hood is connected at its end to the side of thecar by means of the bent angle member 22, which lies in the angle formedbetween the upper sides of the sheets 7 and S, and is secured thereto at23 and to the side of the car 'at 24. Further, the cross hood and sideof the sheets 7 and 8.

Theinside side stake is composed of two angle members 28 'and'29, havingflanges 30 and 31 thereon applied to the side of the car and rivetedthereto at'32 and 33, and havingthe wide flanges 34 and 34* which areriveted together, as shown at 35, throughout their length. The flange 34on the side stake member 28 is bent at its lower end to form the flange35 thereon to overlie the overlapping sheets 7 and 8, and rivets 36secure together the flange 35, the sheets '7 and 8, the connecting anglemember 22 and the angle gusset plate 25. The flange 34 on side stakemember 29 is bent at its lower end to form the flange 37, overlying thesheet 8, and by means of rivets 23$ is secured to said sheet 8 and tothe angle member 22. In this manner we securely bind together the end ofthe cross hood,

- the side of the car, and the inside side stake,

so that all parts are rigidly reinforced; referring to Figs. 2 and 3, itwill be seen that the.

gusset member 25 is connected through the flange 25 by means of therivets 26, to the outside side stake 39, through the flange 40 thereon.The end of the cross hood sheets is further reinforced by means of theflange 41 formed on the end sheet 41 of the hopper to overlie the crosshood sheet 7 as shown in Fig. 7, and is secured thereto at 42; the'endsheet is secured to the side of the car and the outside side stake bythe rivets 26 which also secure thereto the gusset angle member 25. Thelower edge of'the cross hood sheet 7 is further reinforced by the anglemember 9, which is secured thereto by the rivets 43.

The center sill hood 5 as above stated is secured along its lower edgesto the center girder or sill at 6 and meets the slope of the cross hoodon an inclined line and is secured thereto by means of the lateralflanges 44 and 45 formed on the center sill hood, which flanges aresecured to the cross hood sheet 8 by rivets, as shown at 46 and 47. Inthis manner the cross hood and the center sill hood are securely unitedto resist both longitudinal and transverse stresses. In a similar mannerthe center sill hood is united to the cross hood sheet 7* as shown inFig. 1.

In Fig. 4 is shown the perspective of the cross hood and centei girderin which it appears clearly that the cross hood sheets 7 and 8 extendentirely across the car and are sill. The application of the inside sidestake to the cross hood is also herein illustrated. lVe do not confineourselves to the specific construction shown and dlsclosed herein,

but desire to have the advantage of all the variations and modificationswhich fall within the scope of the appended claims.

lVhat we claim is z 1. In a hopper car, a cross hood comprising onesheet bent downwardly along its up per side to form the ridge portion,and a second sheet secured along its upper edge to the lower edge ofsaid ridge portion, and

means for securely connecting said cross hood to the center sill andsides of the car.
